Specification of Letters Patent.

Application filed July 5, 1913.

To all whom it may concern:

Be it known that we, JAooB B. CoNovnI: and EDWARD M. PEACOCK, citizensof the United States, residing at Jersey City, in the county of Hudsonand State of New Jer' sey, have invented certain new and usefulImprovements in Milk-Cans, of which the following is a specification,reference being had therein to the accompanying drawings, forming partthereof.

Our invention relates to milk cans and similar sheet metal containers,and has for a general object the provision of a strong, durable oint atthe juncture of the body and breast of the can, capable of withstandingthe hard usage to which such cans are subjected.

Another object is to provide a joint which will be simple andinexpensive to manufacture, and which will not provide any unevennessesfor the lodgment of decayed milk, but will be smooth and sanitary on theinterior of the can.

A more specific object is the provision of a suitable and convenienthousing for a reinforcing hoop at the joint.

Still other objects and advantages of our invention will appear from thefollowing description.

Joints have heretofore been proposed in sheet metal containers in whichthe edge of one member is received in a recess formed by a double foldin the member to which it is joined, and such a joint is disclosed inthe patent to Samuel C. Davidson, N 0. 417,813, of December 24:, 1889.Such joints, however, have not provided a smooth interior to thecontainer, and are, therefore, not sanitary and suitable for milk canconstruction; and, furthermore, the oints heretofore proposed have notbeen sufiiciently strong and durable for heavy milk cans.

In accordance with our invention, the upper end of the body is prowddedwith an outward offset, and the breast is provided with a double foldforming an annular recess into which the offset upper end of the body isreceived, the inner walls of the recess fitting into the offset so as toform a flush interior joint; and, specifically, in the preferredconstruction, the offset upper end of the body and the inclosing foldfit down upon the inclined wall of the breast.

Still more specifically a reinforcing hoop is provided at the jointwhich is housed within the outer wall of the recess.

Our invention also includes various other features of construction andarrangements of parts, as will hereinafter more fully appear.

We shall now describe the construction embodying our inventionillustrated in the accompanying drawings, and shall thereafter point outour invention in claims.

Figure 1 is a partial central vertical section and a partial elevationof the upper portion of a milk can, showing an interme diate stage inthe fOHlfltlOll of our improved joint. Fig. 2 is a similar view showingthe joint in its finished condition.

In the illustrated embodiment of our in vention, the breast 1 isprovided near its lower end with a double fold forming an annular recess2 with two inner walls 3 and 4 and a downwardly extending outer wall Thecylindrical body 8 is provided at its upper end with an outwardly offsetportion 7 forming an annular shoulder 8 of a width substantially equalto the thickness of the two inner walls 3 and 4 of the recess 2, andthis offset portion 7 is received in the recess 2, and, together withthe inclosing walls 4 and 5 of the recess, fit down upon thefrustoconical or inclined wall of the breast 1. The inner walls 3 and 4of the recess thus fit into the offset and abut against the shoulder 8and form a flush interior oint, which may be finished with solder torender the joint smooth.

' The method of forming this joint will be understood from Fig. 1. Thefold is first formed with the inner walls 3 and 4 of the recess 2vertical and with the outer wall 5 inclined outwardly, as shown, atsubstantially the angleof inclination of the frustoconical portion ofthe breast 1. The upper end of the body 6 is then inserted into therecess 2, and with a suitable tool the two inner walls 3 and 4t and theinclosed upper end of-the body 6 are forced outwardly against the outerwall 5, thereby forming the offset and the shoulder 8, and forming asecurely locked and a sanitary joint. To further reinforce the joint andprotect it from injury from blows and other rough treatment, we providea reinforcing hoop 9 about the body 6 immediately below the oifset andthe shoulder 8. The outer wall 5 of the recess 2 is of such length thatit extends down below the hoop 9, and in the final operation of formingthe joint, this outer wall 5 is forced inward about the hoop and forms ahousing for the hoop, as shown in Fig. :2. This arrangement of the hoopimmediately below the shoulder 8 permits of this convenient housing, andin no wise detracts from the appearance of the can. The joint issanitary and easily formed, and combines great strength and durabilitywith neatness of appearance.

It is obvious that various modifications may be madein the constructionshown in the drawings and above particularly described within theprinciple and scope of our invention.

Ne claiin 1. In a milk can or the like, a body having an outward offsetat its upper end forming an annular shoulder, and a breast provided witha double told with a double inner wall forming an annular recess for thereception of the upper offset end of the body, the double inner wall ofthe recess fitting into the offset so as to form a flush interior jointat the juncture of said shoulder and of the lower end of said wall.

2. In a milk can or the like, a body having an outward offset at itsupper end forming an annular shoulder, and a breast having an inclinedwall and provided with a double fold with a double inner wall forming anannular recess for the reception of the upper offset end of the body,the double inner wall of the recess fitting into the offset so as toform a flush interior joint at the juncture of the said shoulder and thelower end of said wall and the upper offset end of the body and theinclosing fold fitting upon the inclined wall of the breast.

In a milk can or the like, a body having an outward offset at its upperend forming an annular shoulder, a breast provided with a double foldhaving a double inner wall forming an annular recess for the receptionof the upper offset end of the body, the inner walls of the recessfitting into the offset so as to form a flush interior joint at thejuncture of the said shoulder and the lower end of said wall, and areinforcing hoop interposed at the joint and housed within the outerwall of the recess.

4. In a milk can or the like, a body having an outward offset at itsupper end forming an annular shoulder, a breast provided with a doublefold having a double inner wall forming an annular recess for thereception of the upper offset end of the body, the double inner wall ofthe recess fitting into the offset so as to form a flush interior jointat the juncture of the said shoulder and the lower end of said wall andthe upper offset end of the body and the inclosing fold fitting upon theinclined wall of the breast, and a reinforcing hoop interposed at thejoint and housed within the outer wall of the recess.

5. In a milk can or the like, a body having an outward offset at itsupper end fornr ing an annular shoulder, a breast provided with a doublefold having a double inner wall. forming an annular recess for thereception of the upper offset end of the body, the double inner wall ofthe recess fitting into the offset so as to form a flush interior jointat the juncture of the said shoulder and the lower end of said wall, anda re inforcing hoop surrounding the body below the offset and adjacentthereto, the outer wall of the recess extending over and forming ahousing for the hoop.

6. In a milk can or the like, a body having an outward offset at itsupper end forming an annular shoulder, a breast having an inclined walland provided with a double fold having a double inner wall forming anannular recess for the reception of the upper offset end of the body,the double inner wall of the recess fitting into the offset so as toform a flush interior joint at the juncture of the said shoulder and thelower end of said wall and. the upper offset end of the body and theinclosing fold fitting upon the inclined wall of the breast, and areinforcing hoop surrounding the body below the offset and adjacentthereto, the outer wall of the recess extending over and forming ahousing for the hoop.

In testimony whereof we have afiixed our signatures in presence of twowitnesses.
